Semi-Micro Cuvettes, 2.5 mL UV-Grade PMMA, 2 Clear Sides — 500/Case | Globe Scientific

Semi-Micro 2.5 mL UV-Grade PMMA Cuvettes, 2 Clear Sides — 100/Tray, 5 Trays per Case (500/Case)

The Globe Scientific Semi-Micro UV-Grade PMMA Cuvette is a disposable optical cell molded from UV-transparent polymethylmethacrylate with two polished clear sides for precise low-volume measurements. Designed for UV-Vis spectrophotometry, nucleic acid and protein quantitation, and routine absorbance readings, it delivers reliable optical clarity down to the near-UV range. Each unit holds 500 cuvettes packaged as five trays of 100.

Frequently Asked Questions

What wavelength range do these UV-grade PMMA cuvettes support?

UV-grade PMMA transmits well across the visible spectrum and into the near-UV, typically usable from about 300 nm upward. For deep-UV work below roughly 280 nm, quartz cuvettes remain the preferred choice.

What is the usable volume and path length?

These semi-micro cells hold up to 2.5 mL and feature a standard 10 mm path length with a reduced inner chamber, allowing accurate readings on smaller sample volumes than a standard macro cuvette.

Are these cuvettes reusable?

They are disposable and intended for single-use to prevent cross-contamination and avoid solvent-induced clouding. Buying in the 500-count case keeps per-cuvette cost low for high-throughput workflows.

Can I use organic solvents in these cuvettes?

PMMA tolerates aqueous buffers and dilute acids and bases well, but is incompatible with acetonitrile, aromatic, and chlorinated solvents. For solvent-heavy methods, select glass or quartz cells instead.
